Is there a way to turn the boost solenoid off via a switch in AEM?

Basically, I'm trying to figure out if there is a way to have 3 boost levels on one map with AEM. I know I've seen several people say that you can setup a switch to go from hi/low boost... but that would only give me two... so I was thinking maybe there is a way to turn the solenoid off so I can use spring pressure (like the TruBoost can).

Currently I'm using the TruBoost to have 3 levels (spring, setting 1 (~17 psi), setting 2 (~22psi), but I would really like to wire in the solenoid to the AEM so I can do boost by speed.

I know you're thinking why do you need 3 levels? Well, I will be using all three for different purposes... spring for autocross/road course, setting 1 (~17 psi) for daily/street applications, and setting 2 (~22psi) for the drag strip. Obviously I could switch maps, but I was hoping to avoid that if at all possible...

So yeah... Any thoughts/ideas?

Use a toggle switch inline with the power wire for the solenoid? Once the solenoid has no power you will be on just spring pressure. I think you may be able to set up the AEM to turn the solenoid duty cycle to 0% via a switch also.

Hm, that might be an option... I wouldn't have boost by speed if I cut the power from the solenoid, but I wouldn't really need it at that point anyways...

You think there is an additional option in AEM for that? Hm, any idea what its called or where it is?

The switch I'm referring to actually turns the boost target to zero so pretty much the same as turning off the solenoid.
